Abstract

An annual review of the seismicity in the territory of Belarus based on the data of two analog (operated in the first half-year) and seventeen digital stations is presented. A total of 80 events with Кd=4.6–8.4 were recorded all of them being confined to the southern part of the territory, the Soligorsk mining area included. The map of all the event epicenters for 2015 is given. The table of the distribution of the seismic events by their energy classes and seismic energy in months is presented. The maximum values of the seismic energy release fell in August, and the maximum number of the events was observed in July. The level of the seismic energy released in 2015 is the same as in 2014 but 2.18 times lower than its long-time average value for 1983–2014. The number of the events in 2015 is 1.4 times more than their number in 2014 and 1.86 times more than the Nср value for the previous 32 years. The distribution of the earthquakes in the depth intervals layers showed that the earthquake foci are mostly located in the upper 20 km part of the Earth’s crust. However, the foci of 47 earthquakes are located at depths above 10 km. The distribution of all the events in 2015 is represented in real-time. The quiet seismic periods and seismic activation periods were determined. The distribution of the seismic events in the hourly intervals showed the periods of the increase of the seismic events number. The maximum and minimum values N in the seismic event distribution by the days of the week were determined.

2015年白俄罗斯境内地震活动
根据两个模拟台站(上半年运行)和17个数字台站的数据,对白俄罗斯境内的地震活动进行了年度回顾。总共记录了80次事件,Кd= 4.6-8.4,所有这些事件都发生在领土的南部,包括索利戈尔斯克矿区。下面给出了2015年所有地震震中的地图。给出了地震事件按能量等级和月能量的分布表。地震能量释放最大值在8月下降,事件数在7月最多。2015年释放的地震能量水平与2014年相同,但比1983-2014年的长期平均值低2.18倍。2015年的事件数量是2014年的1.4倍,是前32年nnurr值的1.86倍。地震在深度层间的分布表明,地震震源主要位于地壳的上20 km部分。然而,47次地震的震源位于10公里以上的深度。实时呈现2015年所有事件的分布情况。确定了静震期和地震活跃期。地震事件在小时间隔内的分布表现出地震事件数增加的周期。确定了地震事件按周分布的最大值和最小值N。
